Public buildings have overtaken offices in terms of commissioning energy efficiency measures in the second quarter of 2015, a recent survey of 63 senior managers at supplier organisations has been able to reveal.

Within these projects, high-efficiency lighting continues to outperform individual technologies and features in 63% of energy efficient projects – but lighting controls (34%) and general building controls (31%) and solar PV (22%) are not far behind.

The long-term trend of generally wide-ranging capital cost of these projects indicates sustained growth in project size. The average cost started at around £60,000 in 2012, but the median has now jumped to double that – despite a decrease in the volume of the ‘very largest projects’, valued at half a million pounds, in the last two quarters.

In terms of implementing energy efficiency projects, wireless programmable thermostatic radiator valves offer the best ROIs and lowest overall installation costs. The HeatSave wireless TRVs enable users to set specific functioning times for each valve, and, since radiators are individually controlled, occupants are fully capable to maximise the zoning potential and reduce energy consumption in those areas that are not used for longer periods of time (as for example, dining or sitting rooms and kitchens during the night, etc.).

Additionally, the HeatSave wireless thermostatic radiator valves also provide an automatic exercising feature when unused for 7 days, whose purpose is to minimise seizing of radiator valves in warmer months.

All in all, the HeatSave TRVs enable users to achieve some pretty impressive savings, as they will help reduce your heating bills by up to 30%, especially when coupled with the HeatingSave Building Energy Management System.
